Struct FeeSchedule 

pub struct FeeSchedule { /* private fields */ }

Fee schedule: a (taker, maker) fee pair per fee tier, with the key identifying which schedule it is.

Fees are fractions of the traded amount, converted from the on-chain hundred-thousandths (Per100K) representation.

Implementations

impl FeeSchedule

pub fn key(&self) -> FeeScheduleKey

Schedule this perpetual/exchange resolves its fees from.

pub fn is_tiered(&self) -> bool

Whether the rates were reported per tier, rather than filled in from a base rate observed on its own.

False against a pre-v1.1.7.4 deployment, which has no tiers to report: every tier then carries the base rate, and reading a discounted one back tells the caller nothing the base rate did not.

pub fn taker_fee(&self, tier: FeeTier) -> UD64

Taker fee of the given tier.

Out-of-range tiers (the contract bounds them to 0..8 on write) resolve to the base rate.

pub fn maker_fee(&self, tier: FeeTier) -> UD64

Maker fee of the given tier.

Out-of-range tiers (the contract bounds them to 0..8 on write) resolve to the base rate.

pub fn base_taker_fee(&self) -> UD64

Base (tier 0) taker fee.

pub fn base_maker_fee(&self) -> UD64

Base (tier 0) maker fee.

pub fn taker_fees(&self) -> &[UD64; 8]

Taker fee of every tier, base rate first.

pub fn maker_fees(&self) -> &[UD64; 8]

Maker fee of every tier, base rate first.
